Synchronous Transport Module

What does STM mean?

STM is a module that is used in a fiber-optic network, its standard for SDH(Synchronous digital hierarchy). The transmission formate is considered for the main building block diagram for Synchronous digital hierarchies. Apart from the fact that the high rate of the signals is created by multiplexing numerous STM-1 signals, lower rate payload are also mapped into STM-1.
